Block coefficient: 0.650
Length to Beam Ratio: 6.00 : 1
'Natural speed' for length: 21.21 kts
Power going to wave formation at top speed: 50 %

Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 24.10 ft / 7.35 m

- Average freeboard: 16.04 ft / 4.89 m

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 29.9 %
- Above water (accommodation/working, high = better): 111.4 %
Waterplane Area: 25,854 Square feet or 2,402 Square metres
Displacement factor (Displacement / loading): 463 %
Structure weight / hull surface area: 89 lbs/sq ft or 434 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.96
- Longitudinal: 1.43
- Overall: 1.00
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is adequate
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, can fire her guns in the heaviest weather

5 tons search radar
2 tons navigational radar
3 tons primary fire control radar
3 tons navigational radar
4 tons generators
2 tons primary fire control computer

200 tons pumping gear
1500 tons small machine shop

Pointed out in chat that I should probably make this explicit - Earl and I have different ideas about how to best sim a tanker. Resimming his original with 2000 tons of misc weight produced exactly the same range, bunkerage, and weight figures as my new version. The changes actually covered in the refit sacrifice about 125 tons of machine shop space and equipment to add a basic self-defense armament and radar sets while going in to do the life-extension refit.


Speaking of, tweaks and fixes.

I think the way you simmed it works out better, and falls more in line with the fashion most current players sim our oilers.
